how to insert a row in the middle of a google spreadsheet

Question

I am trying to insert a row into the middle of a google worksheet, however cannot find a way in the api documentation,

I cannot add a new row to the bottom as the program that consumes the spreadsheet data(not written by myself) simply ignores new rows added to the bottom.

anyone got any Ideas?

Answer 1

The following code adds a row in the middle of the sheet:

function onOpen() {
  // get active spreadsheet
  var ss = SpreadsheetApp.getActiveSpreadsheet();

  // create menu
  var menu = [{name: "Insert row ", functionName: "insertRow"}];

  // add to menu
  ss.addMenu("Insert", menu);  
}

function insertRow() {
  // get active spreadsheet
  var ss = SpreadsheetApp.getActiveSpreadsheet();

  // get first sheet
  var sh = ss.getSheets()[0];

  // determine number of rows (compensate for header)
  var rows = sh.getMaxRows();

  // insert row in the middle
  var middle = rows/2;
  sh.insertRows(middle);
}

1. It adds a menu item to the existing menu
2. Inserts a row in the middle of the sheet

See example file I've prepared: add row in the middle
